Chapter layout with \structureuservariable and a makeup

[Marco]

Hi,

I fail to use \structureuservariable to print a value on the page
preceding a chapter. Example:

\setuphead [chapter]
  [before=\setups{chap}, command=\myChap]

\startsetups chap
  \startmakeup
    setups\crlf
    structureuservariable foo: \structureuservariable{foo}
  \stopmakeup
\stopsetups

\define[2]\myChap{%
  \startmakeup
    command\crlf
    structureuservariable foo: \structureuservariable{foo}
  \stopmakeup}

\starttext
  \startchapter [title=First][foo=one]
    \input knuth
  \stopchapter

  \startchapter [title=Second][foo=two]
    \input knuth
  \stopchapter
\stoptext


Problems
--------

\structureuservariable does not work with the “before” key. In the
first chapter the value is empty and in the second chapter it has
the value from the first one. That means, it is designed to be used
with the “command” key.

When used with the “command” key, the values are correct. However,
the following chapter text always appears on the same page, even
when a makeup or a manual page break is used. Additionally you have
to mess around with the two arguments of \myChap, which easily leads
to inconsistent spacing (that's why I used the “before” key in the
first place).

\setuphead doesn't seem to support a “setups=…” key, unfortunately.

What would be the solution for this?
